What is the greatest possible error if jamal measured the length of the walkway as 15.5 meters?

a. 0.05 meters

b. 0.5 meters

c. 15.45 meters

d. 15.55 meters

The correct option is A)  0.05 meters.

Step-by-step explanation:

Consider the provided information.

It is given that Jamal measured the length of the walkway as 15.5 meters

Half of the measuring unit is the greatest possible error in a measurement.

Here, notice there is one decimal places. That means we aren’t actually measuring in m, we’re measuring in tenths of a meter.

The measurement 15.5 meters is about 15 m and 5 tenths.  Or 15.5 was measured to the nearest tenths of m, so the measuring unit is 0.1 m.

The greatest possible error is the half of 0.1 m that is 0.05 m.

Hence, the correct option is A)  0.05 meters.
